Yo, what's the agenda?
● What is a MEAN stack?● MongoDB● Express● AngularJS● Node.js
● Q & A
I'm a old school web dev – what does that even MEAN?
LAMP stack
●Linux server on which you’re running an
●Apache web server with
●MySql as a database and
●PHP as the backend language
Ingredients for a decent Web App
● HTML and CSS is a must● JavaScript (jQuery) is expected● PHP● SQL
One language to rule them all
JS devs unite
● Full-stack JavaScript developer● Frontend and backend devs now
work in conjunction using the same language across all layers
Y U NO interested bro!?
What is MEAN, and why it’s GOOD?
● MongoDB as the database● Express as the web framework● AngularJS as the frontend
framework, and● Node.js as the server platform
Advantages of the MEAN stack
● Single language is used in the whole application
● Support for the MVC pattern● JSON is used for transferring data● Node.js’s huge module library● Open source
We now know what is a MEAN stack, lets go home
● how to put it all together● how to install all the 4 parts of the
MEAN stack● basic usage of all 4 of them● https://hackhands.com/how-to-get-start
ed-on-the-mean-stack/has instructions for Mac OS, Windows and Linux
MongoDB
● MongoDB (from "humongous")– open-source document database– JSON-style documents– leading NoSQL database
Installing MongoDB
● https://www.mongodb.org/downloads● download and extract the archive file
to C:\mongodb● create the folder (C:\data\db) to
store the database files● make sure port 27017 is free to use
Running MongoDB and using the MongoDB shell
● running directly and as a service● mongod & mongo binaries● show dbs● use db● show collections● db.todos.insert({title: "MEAN"})● db.todos.find()● http://try.mongodb.org/
Node.js
● Invented by Ryan Dahl in 2009● platform built on Chrome’s JavaScript
runtime called V8– compiles JavaScript code to native
machine code before executing it– event-driven– non-blocking I/O model is perfect for real-
time applications that run across distributed devices

Installing Node.js
● http://nodejs.org/download/● Windows and Mac OS
– run the installer, Next, Next, Next, Finish type of installation
● Linux– configure, make, make install
Running Node.js
● Node.js CLI● console.log('We're MEAN');● node mean.js● NPM (node package manager)
– comes with Node.js installation– registry for public packages (100k+)– local and global installation mode– npm install <package>– npm install <package> -g
Simplest Web server ever
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
Installing Express
● Web application framework for Node.js● npm init● package.json● npm install express --save
Simplest web server ever, part #2
var express = require('express');var app = express();
app.get('/', function (req, res) { res.send('We are MEAN!');})
var server = app.listen(1337, function () { console.log('App @ http://127.0.0.1:1337')})
AngularJS
● Frontend JavaScript framework– Single-page applications– MVC architecture– built and maintained by Google
● Few of the cool features are:– two-way data binding– extended HTML w/ attributes– improved code structure– easier testing through dependency
injection
Downloading AngularJS
● https://angularjs.org/● <script
src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.4/angular.min.js"></script>
● We can do better with Bower– npm install bower -g– Git dependency (http://git-scm.com/
, great tutor https://try.github.io/)– bower install angular– bower_components folder– bower.json
Testrun AngularJS
<!doctype html><html ng-app> <head> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.4/angular.min.js "></script> </head> <body> <div> <label>Name:</label> <input type="text" ng-model="yourName" placeholder="Enter a name here"> <hr>
<h1>Hello {{yourName}}!</h1> </div></body></html>
